SHUTTLE.

, Speciication of Letters Patent.

` Application led April 2, 1912. Serial No. 687,953.

means is provided lfor permitting the shut tle to be quickly andexpeditiously threaded, and for preventing accidental unthreading. Inthe drawings Figure 1 is a plan view of the improvement. Figs. 2, 8 and4 are enlarged sections on the lines 2-2, 3-3, and 4-4,respectively, ofFig. 1. Fig. 5 is a section on the line 5-5 of Fig. 3, F ig; 6 is aperspective view of the eye, and Fig. 7 lis a perspective view ofamodified form of eye. The present embodiment of the invention comprisesa shuttle body l of suitable size and material yof approximately boatshape, and having the pointed ends 2 and 3. The body is recessedlongitudinally in its upper xface, as indicated at 4, and the bobbin 5is held in the recess, on a spindle 6. The thread 7 passes forwardlyfrom the bobbin to the adjacent end of recess 4, and enters a slot 8arranged vertically in the upper face of the body. The eye 9 for theth-read (Fig. 6) is arranged transversely of the slot 8 in a transverseopening in the body, and the thread passes into the eye in a manner tobe described. The eye, as shown in Fig. '6,

is a shell having a longitudinal slot 10 and a transverse slot 11intersecting the longitudinal slot at one end of the transverse slot atthe center of the said longitudinal slot. The transverse slot 11registers with kthe slot 8 of the body of the shuttle, and the threadenters the eye through slot 11. Atits duter end, slot 8 of the body ofthe shuttle communicates with the .inclined portion 12 ofaslotconsisting .o:E aJ portion 13 parallelA with slot 8, and the'mcllned pandthe portion 13 of slot.12"-13 extendsjn- Wardly beyo'nd the eye,stopping short however of the recess 4. The bottom wall of, slot 8 iscurved or inclined (Fig. 2), belng Atflush with the lower edge of slot10 `at the or-l "tion 12.' .At the junction of slots 8 and 12, ithe bodyis cut away to form a recess 14,'

outer side of the eye and with the end pf slot 11 remote from slot 10 onthe inner side of the eye. Slot 12-13 (Fig. 3) is of equal depth withslot 8, the bottom wall 16 being in .the same plane with the bottom wall15 of slot- 8, and 17 connects the slots, the bottomfof the passagebeing on the same level with thewalls` l5and1. The shuttle lbody isprovided with the threadingF recess or chamber 18 at thejunction of s ot8 with recess 4,-the side Walls of slot 8 bein undercut to'form therecess.

lIt will e noted from an inspection of Figs. 4 and 5 that the slot 12-13vis inclined inwardly toward the upper face of the shuttle, so thatwhile the upperedge, or opening of the slot on the upper face of theshut-tie body, is some distance from the side of the body, the loweredge of the slot cuts the said Patented Nov. 12,1912.

so'v

a transverse passage side at the end of the eye, as' indicated at 19 inFig. 4. The intersection 19 l2 of slot 12-13 is at the end of slot 10 ofthe eye, so that the shuttle may be easily threaded merely by engaging abight of the thread with the beak or horn 20, formed by 'theintersection or junction of slot 8 and portion 12 of slot 12-13, and.drawing the thread inwardly toward the bobbin.

When threading the shuttle, a portion of the thread is drawn from thebobbin, and a bight is formed in the said thread and engaged over thebeakorhorn 20. The ends of the bight are then drawn inwardly toward-therecess 4, and the thread slips Ialong in the inclined passage 17 untilit enters the eye through slot 10. The thread when so engaged must bemoved in recisely the reverse direction to become isengaged, and thereis no possibility of such movement on the part of that end of the. bightof thread connected to the bobbin. It will be noted that in addition tobeing hand threading,

the shuttle has no lateral openings except` the ends of the eye, and.for this reason is much stronger than the usual form of shuttle.

The bobbin is held on the usual pin hinged` 'as shown to the shuttle atthe end remote la. sprln as shown. `The pointed ends 2 and -3 are a soprovided with metallic shields or hoods as shown to lprevent wear on theshutltle. 'Preferably the eye is provided at one of portion end with athreaded` portion for engaging the transverse. opening in the body, andthe said end may also be provided with a transverse kerf or slot forengagement by a tool toturn the eye into place. This construction isshown in Fig. 7, and in the'said eye the slots are somewhat differentlyarranged. As shown, the opposite end of the eye 2l from that providedwith the threaded portion Q2 and the kerf 23, is provided with alongitudinally.extending s lot Q4, communicating at its inner end with atransverse slot 25, and at its outer end with an inclined or spiral slot26. The slot 26 extends 'from the outer end of the slot 24 to the end orthe eye. The threaded portion of the eye is solid. The particulararrangement of slot in the said eye is to facilitate the ent-rance ofthe thread.

l claim l. A shuttle comprising a body having a longitudinal recess inits upper face for the bobbin, and having a threading chamber at.

one end of the recess, and having a lateral 'transverse opening on theopposite side of tlie-elianiber'troin the\recess, an eye in the bpeningcomprising a shell having'alongitudinal slot in the opposite`s`de fromthe chamber, and a transverse slot in its upper side intersecting thelongitudinal slot at Vits center at the outer end of the recess, thebody having a vertical slot leading from the chamber toward the adjacentend of the body and registering with the transverse slot of the eye, thebody having a lateral slot at one) side of the vertical slot, the outerend of the lateral slot inclining inwardly and intersecting the verticalslot at its outer end, the body having a transverse passage connectingthe slots at their bottoms, said passage registering with thelongitudinal slot of the eye, the plane of the lateral slot beinginclined at its top toward the vertical slot and cutting the side of thebody at the end of the longitudinal slot of the eye.

2. A shuttle comprising a body having a bobbin recess and a threadingchamber at the front of the recess, and having a transverse opening infront of the chamber, an eye in the opening` said eye comprising a shellhaving a longitudinal slot in its front side and a transverse slotintersecting the longitudinal slot at approximately its center and atthc front end of the transverse slot, the body having a transversepassage in register with the longitudinal slot of the eye and openingat. the side of the body at the end of the longitudinal slot, saidpassage leading forwardly and upwardly and grad- Aually decreasing inwidth toward its for ward end, the body having a vertical slot at theinner side of the passage and communieating therewith and an inclinedslot at the outer side and communicating with the passage, said slotsconverging at the forward end of the passage.

3. In a shuttle, the combination of a shuttle body provided with abobbin cavity, and the transverse passage at one end of the cavity, anapproximately cylindrical eye in the passage, said eye havingintersecting longitudinal and transverse thread slots, and the shuttlebody having an integral threading tongue for guiding the thread into thethread slots of the eye.
